I have added five fragments in my activity. also i have added Theme.Material3.Light.NoActionBar theme to both of my day and night theme in app. when i change theme from quick toggle theme changer, theme is changing but fragment is restarting. attached .gif video for better understanding what i want to tell.

I tried changing android:configChanges="uiMode" but it didn't work as it is not switching theme in app upon changing from system.

Android restarts Activity when theme is changed (configuration change) to ensure everything is drawn according to a new theme. If you use uiMode you inform the system that you will handle the configuration change on your own, in onConfigurationChanged callback, hence no activity and a fragment restart.

Alternatively you can ensure the fragment state is persisted and restored as expected.
